30.91S.182 Shoreline and bank stabilization and flood protection measures.
"Shoreline and bank stabilization and flood protection measures" means measures taken to address erosion impacts and reduce flood damage or hazards to property and buildings and structures, caused by natural processes such as current, flood, tides, wind or wave actions. Stabilization and flood protection measures can be either non-structural or structural.
(1) Non-structural. Shoreline and bank stabilization and flood protection accomplished by preventing or removing development in flood, landslide or erosion prone areas or by preserving or enhancing natural hydrological and biological processes. Such measures may include, but are not limited to, setbacks, buffers, bank or riparian revegetation, wetland restoration, dike removal or relocation, biotechnical stabilization measures or elevation of structures.
(2) Structural. Shoreline and bank stabilization and flood protection accomplished by the physical manipulation of the bank or channel, other than through enhancement of natural hydrological or biological processes. Such measures may include, but are not limited to, floodwalls, dikes, bulkheads, revetments, levees, jetties, channel realignment, and groins. Structural methods range from "soft" structures that are less rigid and incorporate biotechnical or beach enhancement to "hard" structures that are solid, hard surfaces such as bulkheads, retaining walls, bluff walls and rock revetments.
